September 29 (SeeNews) - Japanese firms Kyocera Corp (TYO:6971) and Misawa Homes Co Ltd (TYO:1722) in October will start carrying out verification tests of a house, the entire electricity consumption of which will be met with solar power.

The model house will be located in Nara prefecture. The two companies will work together on the project in cooperation with Tokyo-based Misawa Homes Institute of Research and Development Co Ltd (MHIRD), according to a press release from Thursday.

The electricity will be generated in-house by combining a 6.6-kW Kyocera solar power array with a 7.2-kWh energy storage system. The lithium-ion batteries will be charged with direct current (DC) electricity from the solar cells, which lowers power loss and ensures a 6% higher charging efficiency by making the conversion to alternating current (AC) electricity obsolete.

The testing of the “energy self-consumption house” is part of Misawa Homes’ disaster prevention and reduction solution. In case of power outage, for instance, the building switches to a stand-alone mode, enabling it to use as much as 3 kW of solar power while charging the storage system with the same amount of electricity.
